NASA launched two spacecraft are about to study the Van Allen radiation belts
Radiation is a very common hazards in the work of space exploration and so, agencies such as NASA aerospace always looking for ways to prevent radiation for many obvious reasons. Radiation can be dangerous to astronauts and destroyed the satellite circuits. So why does NASA prepare the unmanned spacecraft on the area's most dangerous radiation in the vicinity of the Earth? In fact, on 23 August to 2 typhoon belt probe radiation (Radiation Belt Storm Probe - RBSP) will be launched into orbit by the Atlas V rocket from Cape Canaveral Air Force Center, Florida and objectives of them is the study of radiation of the Van Allen belt.   Van Allen belt was discovered in 1958 by America's first satellite was successfully launched - Explorer I, and it was named after the discoverer - James Van Allen. They include two radiation belts created by the interaction of the Sun and Earth's magnetic field. The results from the interaction of protons and electrons are electrically trapped in a magnetic field like iron filings attracted enthusiastic a magnet. The magnetic field carries a certain significance by one hand they protect Earth from dangerous radiation from space, but on the other hand, they are also limited to areas where the astronauts and the spacecraft does not the driver.   RBSP mission will explore the two Van Allen belts. Two probes with anti-radiation coating will fly through the area of ​​radiation contained charged particles high in order to find out more about how they are charged by the effects from the sun glare such as hand wound (solar flare) and corona discharge (coronal discharge).   It is no coincidence that NASA wants to learn deeply about the nature of the Van Allen belt. In space weather impacts on the spacecraft, communications networks, power grids on Earth and people. In case of bad weather, such as a large solar storm aimed directly at Earth, it can demolish the whole grid on half the planet and destroy the entire computer. As with humans, this would be a bane for passengers who are traveling on a flight because it will disable vital systems on board.   "It is difficult to predict the effects of the radiation belts on Earth by causing space weather," Barry Mauk, project scientist from the laboratory RBSP applied physics from the University of John Hopkins , Maryland said. "One of the major objectives of the RBSP mission is to use the Earth's magnetosphere as a natural lab to draw the general knowledge of how radiation formation and development in the universe. Vu head is still very much a mystery to be answered. "   As part of Livin With a Star program of NASA, the RBSP mission scheduled lasted 2 years and is controlled from the center of aerospace Goddard in Greenbelt, Maryland.     By: Gizmag ...
